There are certain perks to playing the financial elite - such as the sharp threads and sunglasses Harrison Ford, Liam Hemsworth and Gary Oldman get to show off in the espionage thriller Paranoia.

"It was a nice change of pace to come to work, put on a nice suit and stay clean all day," says Hemsworth (The Hunger Games).

The perks get even better in Paranoia, directed by Robert Luketic (out Oct. 4, 2013). In one scene, Jock Goddard (Ford) hands his hotshot new hire the keys to a $100,000-plus Fisker luxury hybrid car, leaving him "speechless," says Hemsworth. "He cannot believe all of this is happening."

But the business world shows its gnarly side as the ambitious upstart is blackmailed by a corporate titan (Oldman) to spy on his business competitor. "I'm a pawn in a master plan. And as it starts to get deeper and more dangerous, it's clear this fancy life is not what I thought," says Hemsworth.

Ford says he buzzed his hair "to the shortest possible" length to play his high-flying character. "The look was something I had not had before. And I thought it added strong character value."

Director Luketic says word of the iconic actor's short 'do "made a lot of people nervous" before he showed it on the set.

"Are you kidding?" says Luketic. "But I had complete faith in him. I am all for it when an actor wants to embrace the character. And he pulled it off. He looks really good in the movie and he brought his acting A-game."

Ford relished the opportunity to re-tangle with Oldman; the duo memorably collided in 1997'sAir Force One.

"There is a real contest of wills between the two of us here," says Ford of Paranoia, adding that the film's title is appropriate for the high-stakes business empire. "It's a world that is well served by being even more paranoid than the characters actually are."
